using System.Security;
using System.Security.Permissions;

namespace Samples
{
  public class SecurityPermissionFlagSample
  {
    public static void Main()
    {
      SecurityPermission sp1 =
        new SecurityPermission(
          SecurityPermissionFlag.Assertion);
      SecurityPermission sp2 =
        new SecurityPermission(
          SecurityPermissionFlag.ControlEvidence);
      SecurityPermission sp3 =
        new SecurityPermission(
          SecurityPermissionFlag.Execution);
      SecurityPermission sp4 =
        new SecurityPermission(
          SecurityPermissionFlag.SkipVerification);
      IPermission ip = sp1.Union(sp2);
      ip = ip.Union(sp3);
      ip = ip.Union(sp4);
      Console.WriteLine(ip);
    }
  }
}

The output is:
